Los Angeles has no shortage of agencies willing to run your Facebook and Instagram ads. That is not the problem. The problem is that "we run Meta ads" describes a genuinely enormous range of skill, structure, and honesty, and the difference between a good agency and a mediocre one rarely shows up in the initial pitch meeting.
This is not a pitch for any particular agency. It is a checklist for evaluating any agency you are considering, so you can tell the difference before you sign a contract rather than three months and several thousand dollars into one.
Ask to See Real Account Structure, Not Just Case Study Results
Case studies are marketing material, and marketing material is, by definition, curated. A more useful request is to see an anonymized example of how an agency actually structures a client's ad account: campaign organization, budget allocation between prospecting and retargeting, and how they approach creative testing. An agency that hesitates to show this, or gets vague when asked, likely does not have a repeatable, disciplined process behind the results in their case studies.
Ask How They Report on Performance
There is a meaningful difference between an agency that reports reach, impressions, and engagement, and one that reports cost per acquisition, return on ad spend, and actual revenue generated. The first set of metrics is easy to make look good. The second set is the one that actually reflects whether the campaigns are making your business money. Any legitimate agency should be comfortable being evaluated against business outcomes, not vanity metrics, and the FTC's advertising guidance is explicit that performance claims made to clients and customers alike need to be truthful and substantiated, not just impressive-sounding.
Understand Their Pricing Model Before You Sign Anything
Agencies typically charge a flat monthly fee, a percentage of ad spend, or a performance-based structure tied to results. None of these is inherently better, but each creates different incentives. A percentage-of-spend model can quietly incentivize an agency to recommend increasing your budget even when the account has not yet earned it. Ask directly how their fee structure might influence their recommendations, and watch how honestly they answer.
Look for Experience With Businesses Like Yours
Meta advertising for an ecommerce brand selling a $40 product looks fundamentally different from Meta advertising for a B2B service business with a six-figure average contract value. An agency with deep experience in one does not automatically transfer that expertise to the other. Ask specifically about their experience with businesses at your price point, your sales cycle length, and your industry, rather than accepting general Meta Ads experience as sufficient.
Ask What Happens When a Campaign Underperforms
Every account has underperforming stretches. What separates a strong agency from a weak one is not the absence of bad weeks, it is the process for diagnosing and responding to them. Ask an agency to walk through a real example of a campaign that struggled and what they actually did about it. An agency that cannot produce a specific, honest example is either too new to have faced the situation or unwilling to discuss it candidly.
Watch for These Red Flags
Guaranteed results are one of the clearest warning signs in this industry, since no legitimate agency can guarantee a specific return on a channel with as many variables as paid social. Long-term contracts with no exit clause, vague reporting that avoids hard numbers, and an unwillingness to explain their strategy in plain language are all signs worth taking seriously. A good agency should be able to explain what they are doing and why in terms you actually understand, not hide behind jargon to avoid scrutiny.
Check References, Not Just Testimonials
A testimonial on an agency's website was selected by the agency itself, which makes it a poor substitute for an actual reference conversation. Ask to speak directly with one or two current or recent clients, ideally in a similar industry or at a similar spend level, and ask them specifically about responsiveness, transparency during rough patches, and whether the agency's reporting matched what they actually saw in their own sales numbers. A confident agency will not hesitate to connect you.
Local Presence Still Matters for the Right Reasons
Working with an agency based in Los Angeles is not necessary for every business, but there are real advantages for companies serving the LA market specifically: familiarity with local competitive dynamics, neighborhood-level audience nuances across a genuinely enormous and varied metro area, and the ability to meet in person when a campaign needs a deeper strategic conversation than a video call easily allows.
Understand the Contract and Onboarding Before You Commit
Beyond the strategic questions, the practical terms of an engagement deserve equal scrutiny. Ask how long onboarding typically takes before campaigns actually launch, since a vague or unusually long timeline can signal a team that is understaffed relative to how many clients they have taken on. Ask what the exit process looks like if the relationship does not work out, including who retains access to ad accounts, creative assets, and historical performance data. A confident, established agency will have clear, matter-of-fact answers to all of this, because they have been through it before with other clients.
Trust Your Own Read of the Conversation, Too
Beyond every checklist item, pay attention to how an agency handles the sales conversation itself. A team that listens carefully to your specific business before proposing a strategy is a better sign than one pitching the same generic package they clearly present to every prospect. If something about the pitch feels rehearsed or evasive when you ask a direct question, that instinct is usually worth trusting.
Making the Final Decision
After the pitch decks and case studies, the decision usually comes down to a simpler question: does this team demonstrate the kind of rigor, honesty, and structure you would want managing a meaningful piece of your marketing budget. Our breakdown of what actually separates a strong Meta Ads approach from a generic one covers what that rigor looks like in practice, beyond the pitch.
